Mobile information terminal equipment and portable electronic apparatus

Abstract

The objective of the present invention is to have a desired screen displayed with shortened waiting time in using functions for the electronic note, etc., while engaging in telephone talk. Another prime objective of the present invention is to achieve an easy-to-use mobile information terminal equipment which also functions as an electronic note, word processor, personal computer, and so on. In transitting from telephone mode (cover closed status) to information terminal mode (cover opened status), the screen to be displayed is determined to be either a historical information, talk log information, or user setting screen. This enables the user to obtain the desired screen with fewer number of operations and with less waiting time.

What is claimed is: 
     
       1. A mobile information terminal comprising: a slidable cover that covers a part of a surface of said mobile information terminal equipment, said slidable cover having an aperture through which a portion of the surface of said mobile information terminal equipment is viewable even when said slidable cover is in a closed position, a detector for detecting whether said slidable cover is in an open position or a closed position; and a display control unit operatively connected to said detector, said display control unit controlling an input display unit to display the information in a landscape orientation when said slidable cover is in the open position, and in a portrait orientation when said slidable cover is in the closed position. 
     
     
       2. The mobile information terminal equipment of claim 1, further comprising: a display unit for displaying information on a display area in a part of the surface of said mobile information terminal equipment;   a location detector for detecting a location of said slidable cover; and   a display switch for changing a size of said display area and a display direction of information according to the location of said slidable cover detected by said location detector.   
     
     
       3. A portable electronic apparatus, comprising: an input display unit for inputting information and displaying information;   a key panel with switches;   a body with said input display unit and said key panel allocated on a front longitudinal surface thereof,   a slidable cover mounted on the surface of said body for opening/closing said input display unit;   a detector for detecting whether said slidable cover is in an open position or a closed position; and   a display control unit operatively connected to said detector, said display control unit controlling said input display unit to display the information in a landscape orientation when said slidable cover is in the open position, and in a portrait orientation when said slidable cover is in the closed position,   wherein the landscape orientation has a longitudinal direction parallel with the longitudinal direction of said body, and   wherein the portrait orientation has a latitudinal direction parallel with the latitudinal direction of said body.     
     
     
       4. The portable electronic apparatus of claim 3, wherein said slidable cover selects one of said input display unit and said key panel and protects a covered other part of said body.   
     
     
       5. The portable electronic apparatus of claim 3, further comprising: a rail on said body for sliding said slidable cover.   
     
     
       6. The portable electronic apparatus of claim 5 wherein, said detector is a switch on said rail for detecting open/closed position of said slidable cover.   
     
     
       7. The portable electronic apparatus of claim 5, further comprising: an opening/closing support projection on said slidable cover and on said rail for keeping the slidable cover in its opened/closed position. 
     
     
       8. The portable electronic apparatus of claim 5, further comprising: a projection on said rail for preventing the slidable cover from falling off said body.   
     
     
       9. The portable electronic apparatus of claim 5, further comprising: a slide operation support projection on said slidable cover for making said slidable cover slide smoothly against said rail.   
     
     
       10. The portable electronic apparatus of claim 3, further comprising: a support projection on said surface of said body for supporting an inside surface of said slidable cover.   
     
     
       11. The portable electronic apparatus of claim 3, further comprising: a slidable cover shaped such that part of said input display unit is visible even when said slidable cover is in a closed position.   
     
     
       12. The portable electronic apparatus of claim 3, further comprising: a transparent part on said slidable cover.   
     
     
       13. The portable electronic apparatus of claim 3, further comprising: a plurality of convex projections on said slidable cover for facilitating a slide operation.   
     
     
       14. The portable electronic apparatus of claim 3 further comprising: said display control unit changing a size of said a display area and a size of the display information displayed by said input display unit.   
     
     
       15. A portable electronic apparatus comprising: an input display unit for inputting information and displaying information; a key panel with switches; a body with said input display unit and said key panel allocated on surface thereof, and;   a slidable cover mounted on the surface of said body for opening/closing said input display unit, a detector for detecting whether said slidable cover is in an open position or a closed position; and a display control unit operatively connected to said detector, said display control unit controlling an input display unit to display the information in a landscape orientation when said slidable cover is in the open position, and in a portrait orientation when said slidable cover is in the closed position, said slidable cover having an aperture through which a portion of said input display unit is viewable even when said slidable cover is in a closed position.   
     
     
       16. The portable electronic apparatus of claim 15 further comprising: a transparent material covering said aperture.
